Attachment for gasoline tanks



ATTACHMENT FOR GASOLINE TANKS Filed Dec. 12, 1935 ATTORNEYS AT ENT Price ATTACHMENT Foa GASOLINE vTANKS Robert A. mue, cincinnati, ohio Application December 12, 1935, Serial No. 54,090 4 claims. `(ci. 22o-86) The present invention relates to an attachment for gasoline tanks which will prevent the removal o! the contents of the tank by syphoning or by a similar means.

i An object of the invention is to provide an antitheft attachment for tanks which will eectively prevent syphoning or the like, whilst allowing a free and unobstructed passage for gasoline introduced into the tank.

Another object of the invention is to provide an attachment which may be manufactured at a* small costfis of simple design and capable of f1tting all types of gasoline tanks.

A further object is to provide an attachment 15. which may be conveniently fastened to the inside wall of a gasoline tank beneath the inlet opening thereof.

Other objects will be apparent from the following specication, in which: 2 0` 1 is a fragmental view of a gasoline tank showing my anti-theft attachment in cross section and positioned beneath the inlet opening.

Fig. 2 is an enlarged cross sectional view taken on line 2-2 of Fig. 1. 25 l Fig. 3 is a plan view of a blank from which my attachment is formed. l 1; The embodiment of my invention consists of a conventional gasoline tank 5 having an inlet f opening 6 which is positioned upon its upper wall 30 1. The inlet opening may be of any shape whatever to conform to the particular body style of the automobile, or the like. upon which the tank is positioned, provided the shape does not interfere with the free flow of gasolinebeing supplied a5 to the tank. Generally the anti-theft attachment 8 is positioned on the inside wall of the tank beneath the inlet opening. The attachment has a curved bottom portion (Fig. 1) subjacent the opening to readily change the direction of the 40 downowing liquid to an upward movement along the inclined straight portion of the bottom and thence to the mouth of the device. The attach7 nient also has an initially deep and narrow channel formed by the curved bottom portion and the.

45 sides of the device (Fig. 2) which gradually changes to a shallow and wide channel due to the upward inclination of the bottom and the diverging direction of the sides. This construction provides a uniform dimension for the channel to facilitate -the passage of liquid therethrough.`

The mouth of the device is situated close to the Upper wall of the tank for two obvious reasons:

r'st, to allow the tank to containthe maximum ainount'of gasoline without a backward vflow of 55 liquid in the attachment, and secondly, to provide 9llrved pvrtionsubiacent an anti-theft device which is inaccessible. A rod r other protecting means Ais placed' over the `mouth to doubly insure inaccessibility,to the contents of the tank. The anti-theft attachment 8 has a bottom 9 5 which is provided with a curved portion Il! and a straight portion II. The straight portion extends upwardly to the mouth I2 of the device. Side walls .I3 and I4, integral with the bottom 9, diverge outwardly to the mouth I2 (Fig.--2). The 10 upper free ends of the side walls andthe free end of the bottom are bent outwardly to form flanges I which may be soldered, welded or otherwise fastened to the inside surface of the -wall 1. A protecting means which conveniently takes the form of a horizontal rod I6 is fastened to the side walls I3 and I4 and extends transversely of the mouth I2.

Fig. 3-is a plan view of a blank I'I punched from a sheet of suitable material. The side walls 20 ,l

I3 and I4 are formed by bending the blank along the dotted lines I8. The edges of the curved bot--v tom portion IU are then soldered to the curved edges I 9 of the side Walls. The free ends of the,

device are bent at right angles to the sides thereof along the dotted lines to form fastening means when the device is positioied on the inside surface of the tank. Two annular holes 2| may be provided in the sides I3 and I4 to receive the rod. A breather hole 22 is punched in the sides of my attachment to prevent overflowing in the inlet opening, caused by bubbling in the supplied gasoline when a large amount of the liquid is introduced into the tank.

What is claimed is: 1. In an anti-:theft attachment for gasoline 4 tanks the combination with a tank having an inlet opening, ofI a narrow extended `mouth, of a bottom comprising a downwardly extending curved portion subjacent the inlet opening and a straight portion extending upwardly to the mouth, of two side walls engaging the longitudinal edges of the bottom and diverging outwardly to the mouth, of a ange formed about the free ends of the side walls and the curved bottom portion and adapted to engage the inner side of the tank about the inlet opening and of a horizontal rod positioned transversely of the mouth.

2. In an anti-theft-*attachment for .gasoline tanks the combination with a tank having an inlet opening, of a narrow,'extended mouth,A of a bottom comprising a downwardly extending the inletopening and 55 a straight portion extending fromethe curved engaging the longitudinal edges of the bottom portion upwardly to the mouth', of two side walls and diverging outwardly to the mouth and means engaging the longitudinal edges o; the bottom adapted to fasten theside walls and the free end and diverging outwardly to the mouth, of a ofthe curved portion ci.' the bottom to the inner 5 ange formed about the free ends of the side side of the tankl -about the inlet opening.y 5 walls and the curved bottom portion and adapted 4.
